摘要
Abstract
The excavation for deep foundation pits of Ji'nan West Railway Station and its auxiliary projects were studied in this paper. Based on the construction project of foundation pit, a mechanic model for excavation was firstly proposed. Then the Mohr-Coulomb model was used to simulate the elastoplastic property of soil by site investigations and soil test datas. The ABAQUS software was used to analyse the process of stepped excavation for the foundation pit. The results show the rules of force and deformation of complicated deep excavations. Finally, some numerical examples were given.关键词
